These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
In this exemplary embodiment, first, a method for invoking a camera of a virtual machine of an android system is provided, and referring to fig. 1, the method may include the following steps:
step S101: a third party application program on the virtual machine requests to call a client camera;
step S102: the virtual machine detects whether the third party application program sends an intent request message when requesting to call a client camera;
step S103: when detecting that the third party application program sends an intent request message when requesting to call a client camera, a transformation camera application program in the virtual machine receives the intent request and sends camera call request data of the third party application program to the client through a service process of a server;
step S104: when detecting that the third party application program does not send the content request information when requesting to call a client camera, the android system framework layer of the virtual machine intercepts call request data of the third party application program and sends the call request data to a modified camera application program in the virtual machine, and the modified camera application program in the virtual machine sends the camera call request data of the third party application program to the client through a service process of the server;
step S105: the virtual machine receives image or video data sent by the client through a service process of the server.
As shown in fig. 3, the virtual machine system includes a user side device, a server and a virtual machine, where the user device includes at least a client and a camera, the server performs data transmission between the client and the virtual machine through a service process, and when the server is started, the virtual machine is started and corresponding ports on the virtual machine side and the client side are monitored. When a user operates a third application program on the virtual machine through the client, and the third party application program execution function is to be used for the client section camera, the third party application program on the virtual machine can request to call the client section camera; at this time, the virtual machine detects whether the third party application program sends the content request information, and specifically, the third party application program can be a pre-installed camera application program in the android system of the virtual machine, or can be an application program which is installed by a user, such as an application of a beauty camera, a WeChat, a payment bank and the like; the method comprises the steps that the content request information is aimed at a call request sent by a default pre-installed camera application program, when the content request information is detected, a modified camera application program in a virtual machine directly receives the content request information, and call request data sent by the pre-installed camera application program is sent to a client through a service process in a server; when the third party application program requesting to call the camera is not a preloaded camera application program, an android system framework layer (framework layer) in the virtual machine intercepts call request data of the third party application program and sends the call request data to a reconstruction camera application program in the virtual machine, and the reconstruction camera application program in the virtual machine sends the call request data to a client through a service process through a port between the reconstruction camera application program and a server.
According to the camera calling method of the android system virtual machine, the function of camera related operation is provided for the third party application on the virtual machine, and the camera related function operation of the third party application on the virtual machine is implemented by the android virtual machine through the physical camera.
Next, each step of the above-described method in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 3.
In one embodiment, the remodelling camera application program in the virtual machine starts a visual interface while sending the camera call request data of the third party application program, and receives and displays the image or video data sent by the client through the service process of the server in real time. Specifically, some third party applications need to preview the captured picture or video in real time, for example, when the user wants to capture the video, the user needs to display a video picture to ensure whether the picture is the picture that he wants to capture, and at this time, the virtual machine needs to receive the picture information in real time and display the picture in real time, so that the modified camera application in the virtual machine needs to start a visual interface to display the captured picture.
In one embodiment, the visual interface is a picture-in-picture mode interface or a small window mode interface or a full window mode interface. Specifically, according to different third party applications, different visual interfaces can be set, for example, when the third party application is a preloaded camera application program, the visual interfaces can be displayed in full screen; if the third party application is WeChat, the visual interface can be in a picture-in-picture mode display or a small window mode display, and the display mode can not influence the normal use of WeChat; the specific visual interface display may be set according to the needs of the user, and is not particularly limited herein. Because the remodelling camera in the virtual machine needs to start a camera call request of the third party application and also needs to start a visual interface, the remodelling camera application program in the virtual machine at least comprises: camera rights, read-write external storage rights, audio recording rights, positioning rights, and camera feature declarations.
In one embodiment, the virtual machine monitors the process of the third party application program, and when the process of the third party application program is monitored to end shooting, the modified camera application program in the virtual machine receives and displays the image or video data sent by the client through the service process of the server. Specifically, according to the difference of the third party application, the shooting picture may not need to be monitored in real time sometimes, or when the running speed is affected due to the fact that interaction between the virtual machine and the client is increased by the fact that the shooting picture is monitored in real time, the shooting process can be monitored, interaction is performed when the shooting execution is completed, and shot image or video data is received.
In one embodiment, the call request data of the third party application program is sent to the camera application program in the virtual machine by modifying the android system framework layer camera class file code of the virtual machine to set system attributes or send broadcast notification or directly start a service process. Specifically, the calling information is intercepted by carrying out code transformation on the camera class files of the android system framework layer of the virtual machine; for example, the system attribute is set through the transformation code, and when the system attribute changes after the call request data is intercepted, the call information is sent to the transformation camera application program of the virtual machine; for example, the method can also be that a broadcasting notification is sent when the request data to be called is intercepted through code transformation, and calling information is sent to a transformation camera application program of the virtual machine; for example, the method can also be a modified camera application program which directly starts a service process to send calling information to a virtual machine through code modification when the calling information exists, and for example, the method can be used for monitoring specific buttons of some common mainstream application programs such as WeChat, QQ, payment treasures and the like at a frame layer, such as a video shooting button of the WeChat application program, and directly starting the service process to send the calling information to the modified camera application program of the virtual machine when a user clicks a picture or the video shooting button is monitored.
The second embodiment provides a camera calling method of the android system virtual machine, which comprises the following steps:
step S201: the user client receives camera calling request data sent by a camera reconstruction application program in the virtual machine through a service process of the server;
step S202: the client calls a camera to shoot images or videos;
step S203: and the client sends the image or video shot by the camera to a camera application program in a virtual machine through a service process of the server.
Specifically, when the client of the user receives, through a corresponding port on the client side, camera call request data sent by a camera application program in the virtual machine transformed by the server through a service process, and then sends an intent request to the camera, namely a physical camera of the user equipment, so as to call the camera to shoot an image or a video, and the shot image or video data is sent to the camera application program in the virtual machine through the service process of the server.
In one embodiment, the client sends the image or video shot by the camera to a remodelling camera application program in the virtual machine in real time through a service process of the server. Specifically, the client can send the shot image or video to the reconstruction camera application program in the virtual machine in real time, so that the preview can be performed in the shooting process, and the shooting accuracy is ensured.
In one embodiment, after the client receives the shooting information from the third party application program monitored by the virtual machine, the image or video shot by the camera is sent to the modified camera application program in the virtual machine through a service process of the server. Specifically, after the virtual machine monitors that shooting ends and sends shooting end information data to the client, the client directly sends a shot image or video to a modified camera application program in the virtual machine after shooting ends according to the received shooting end information data.
According to the camera calling method of the android system virtual machine, the function of camera related operation is provided for the third party application on the virtual machine, and the camera related function operation of the third party application on the virtual machine is implemented by the android virtual machine through the physical camera.
